

Using Blank CDs and DVDs

NOTE: Ensure that you observe all copyright laws when creating CDs or DVDs.

NOTE: The types of CD or DVD drives offered by Dell may vary by country.

NOTE: CD-RW/DVD combo drives cannot write to DVD media. If you have a CD-RW/DVD combo drive and you experience recording problems, check for

available software patches on the Sonic support website at www.sonic.com.

NOTE: Most commercial DVDs have copyright protection and cannot be copied using Sonic DigitalMedia.

CD-RW drives can write to CD recording media only (including high-speed CD-RW) while DVD-writable drives can write to both CD and DVD recording media.

Use blank CD-Rs to record music or permanently store data files. After creating a CD-R, you cannot write to that CD-R again (see the Sonic documentation for

more information). Use blank CD-RWs to write to CDs or to erase, rewrite, or update data on CDs.

Blank DVD+/-Rs can be used to permanently store large amounts of information. After you create a DVD+/-R disc, you may not be able to write to that disc

again if the disc is "finalized" or "closed" during the final stage of the disc creation process. Use blank DVD+/-RWs if you plan to erase, rewrite, or update

information on that disc later.

Helpful Tips

l Use Microsoft®Windows®Explorer to drag and drop files to a CD-R or CD-RW only after you start Sonic DigitalMedia and open a DigitalMedia project.

l Use CD-Rs to burn music CDs that you want to play in regular stereos. CD-RWs do not play in most home or car stereos.

l You cannot create audio DVDs with Sonic DigitalMedia.

l Music MP3 files can be played only on MP3 players or on computers that have MP3 software installed.

l Commercially available DVD players used in home theater systems may not support all available DVD formats. For a list of formats supported by your

DVD player, see the documentation provided with your DVD player or contact the manufacturer.

l Do not burn a blank CD-R or CD-RW to its maximum capacity; for example, do not copy a 650-MB file to a blank 650-MB CD. The CD-RW drive needs 1–2

MB of the blank space to finalize the recording.

l Use a blank CD-RW to practice CD recording until you are familiar with CD recording techniques. If you make a mistake, you can erase the data on the

CD-RW and try again. You can also use blank CD-RWs to test music file projects before you record the project permanently to a blank CD-R.

l See the Sonic website at www.sonic.com for additional information.

Connecting Your Computer to a TV or Audio Device

Your computer has an S-video TV-out connector that, together with a standard S-video cable (available from Dell), enables you to connect the computer to a

TV.

Your TV has either an S-video input connector or a composite video-input connector. Depending on what type of connector is available on your TV, you can use

Before Working Inside Your Computer

Use the following safety guidelines to help protect your computer from potential damage and to help ensure your own personal safety.

CAUTION: Some of the parts described in this chapter may be replaceable by a certified service technician only and are not customer-

replaceable.

NOTICE: To avoid losing data, save and close any open files and exit any open programs before you turn off your computer.

CAUTION: Before you begin any of the procedures in this section, follow the safety instructions in the Product Information Guide.

CAUTION: Handle components and cards with care. Do not touch the components or contacts on a card. Hold a card by its edges or by its metal

mounting bracket. Hold a component such as a processor by its edges, not by its pins.

NOTICE: Damage due to servicing that is not authorized by Dell is not covered by your warranty.

NOTICE: When you disconnect a cable, pull on its connector or on its pull-tab, not on the cable itself. Some cables have a connector with locking tabs; if

you are disconnecting this type of cable, press in on the locking tabs before you disconnect the cable. As you pull connectors apart, keep them evenly

aligned to avoid bending any connector pins. Also, before you connect a cable, ensure that both connectors are correctly oriented and aligned.
